The latest example of biomimicry in robotics to cross our desk is from German electrical automation company Festo, which has used the shape of the acquatic, flightless bird to construct two different types of bionic penguins. The AquaPenguins use the bird's hydrodynamic body contours and wing propulsion to allow the robot to maneuver in cramped spaces, turn on the spot and, unlike their real-life counterparts, swim backwards. The larger helium-filled AirPenguins use the same principles to lift the usually flightless bird into the air.
